Abstract
A safety valve is positioned in supply plumbing that supplies a fluid medium such as natural gas to a point of use structure such as a home. A mechanical actuator is provided remote from the safety valve but mechanically connected to the safety valve. This allows the actuator to be positioned, for example, directly on the point of use structure, avoiding the need for separate bracing for the valve. The valve can be provided with a tee fitting or can be a separate gate valve. The mechanical actuator can be actuated by seismic disturbance, manually, or by activation by remote sensor or home security system.
